The new Polar fitness watch will measure the power of your exercise

Polar announced today two new training trackers: the most expensive Vantage V and the cheapest Vantage M companion. Let's start with the bigger and more expensive watch. The Vantage V costs $ 499.90 and includes a new optical heart rate sensor with nine LEDs on two different wavelengths (green and red). This, the company says, should make its heart rate readings more accurate.

The biggest addition to the watch is its power measurements for the race. This is a relatively new measure, but you might recognize it because of products like Stryd. It essentially measures the wearer's performance, in the same way that cyclists measure their generated watts. Runners will probably appreciate this for training purposes. It does not support LTE, although it has a built-in GPS. Polar adds: It charges a custom charger and should last 40 hours. It is also resistant to water and swimming. The watch features a 1.2-inch, 240-by-240 touch screen, which turns off once users enter their training mode. It is available in white, black and orange.

The Vantage M, cheaper, costs $ 279.90 and has the same technology, except the touch screen and current detection. Unlike the Vantage V, you can change the bands of the Vantage M. The watch also does not include any of the features of the signature software Polar, the "recovery mode", which analyzes the previous workouts of the carriers to determine the necessary time. put it back. Both watches are available for pre-order on the Polar website and will be available in October.
